Abstract

A biological certified reference material for nine 2,3,7,8-chlorine substituted dibenzo-p-dioxin and dibenzofuran congeners and nine common polychlorinated biphenyl congeners is available for the first time. This material (CARP-1) is in the form of a slurry comprising approximately 9 g of carp homogenate sealed in a glass ampoule. The only foreign materials in the slurry are an antioxidant added to prevent rancidity and water to facilitate homogenization and ampouling. CARP-1 was found to be homogeneous and stable with respect to its organochlorine concentrations under room as well as elevated temperature storage conditions. The minimum projected shelf life for this material is 5 years. © 1995 Springer-Verlag.
